用电源管理芯片简化 ACPI规范:The Advanced Configuration and Power Interface
specification (ACPI; [1]), written by a consortium
representing Intel, Microsoft and Toshiba, attempts to evolve
the current collection of power management methods and
configuration interfaces into a well-specified and unified
power management and configuration mechanism. The key
objective in the ACPI specification is to transfer all control of
power management and configuration functions to the
operating system, thus enabling Operating System Directed
Power Management (OSPM). ACPI-compliant systems will
benefit from a robust interface for configuring motherboard
devices, a versatile power management interface enabling a
wide variety of solutions with full operating-system support,
and not lastly, a realm of new, intelligent possibilities added
to the already broad span of PC uses.
The HIP6501A is the first Intersil IC to be used in conjunction
with a second chip to provide a complete ACPI-sanctioned
motherboard power regulation solution. The
HIP6501A/HIP6021 chip sets produce the processor core,
GTL bus, memory controller hub, and clock chip voltages, as
well as the SDRAM memory, 3.3V and 5V dual voltage
planes [2, 3] necessary for a complete PIII-Whitney system
implementation.
